Cam bearing, yes, but I doubt it.

Odds are valves need adjustment, and or the cam chain tensioner need to be cleaned, rebuilt, or replaced, all of which is common for the 250.

Due to the solid lifters, it's going to sound noisy.

You adjust the valves yourself if your handy, if not have it done by a professional.


The cam chain tensioner needs servicing, or replacement part # 12048

Here's a how-to guide


Hope this helps.

All else fails, if it does have bearing issues, get another engine, there plentiful, and cheap.
IMHO the engine is not worth rebuilding, I compare them to a BIC lighter.

I'm not your mom and I'm not paying for your parts, so do whatever you want with your own bike.
